RECTAL BLEEDING. Blood in the stool or on the tissue. DEFINITION: Rectal bleeding can be caused by hemmorrhoids (external or internal), colon polyps, ulcers, broken blood vessels, diverticula, inflammation of the bowel, diarrhea, infectious parasites and diseases, tumors, rectal fissures, excoriations and other problems. Therapy. Therapy is directed at the cause. First of all it is important to figure out the problem. This may take a number of physician visits. A popular and effective tool is the colonscope and the sigmoidiscope. These are fiber optic devices that can be inserted up the rectum and then the physician can view the inside of the rectum and the colon to see if the problem can be identified. If one is having hemmorrhoids or an excoriated rectal area it is best to stop using toilet paper and to wash the rectal area with soap and water after each bowel movement. This technique is to get a large cup that can hold at least one quart of water. Put your left hand in the water and put some liquid soap on your left hand. Holding the cup with the right hand, pour the water down the middle area of your buttocks and use your left hand to guide the water and the soap over the rectal area, using your left hand to wash the rectal area. Once washed with soap and water, use another cup of water to rinse the soap off the rectal area. Anusol HC suppositories are commonly used for painful hemmorrhoids, as is some of the excellant over the counter products for this common malady. As a general rule, bright red blood usually comes from the rectal area, while the black stools come from blood from the stomach area. Other tests are barium enema xrays and the swallowing of xray material to get a GI follow through xray. It is important to find out where the blood is originating from.
